As a Computer Network Engineer, your resume should highlight technical skills and structured problem-solving. Use a reverse-chronological template to showcase your most relevant experience first. Stick to one page unless you have extensive, job-related experience (then two pages max). ATS-friendly fonts like Calibri or Arial at 11pt are ideal—avoid fancy fonts that hide your skills from automated scanners.
Keep sections clear: Contact Info, Summary, Experience, Technical Skills, and Certifications. Use bullet points over long paragraphs. For example, instead of writing "Managed networks," say "Reduced downtime by 30% through proactive monitoring."
Common mistakes: Columns for skills (ATS can’t read them), tiny fonts (8pt!), or graphics that look unprofessional. Your resume should read like a clean, easy-to-scan document—think of it as a technical spec sheet for your career.
